Hulubelu is an elliptical, 4-km-long caldera or volcano-tectonic depression in SE Sumatra. The caldera floor, about 700 m above sea level, is surrounded by steep walls. Post-caldera volcanism formed central cones and basaltic and andesitic flank volcanoes. The age of its latest eruptions is not known, although solfataric areas, mud volcanoes, and hot springs occur at several locations. Thermal areas are aligned NE of and parallel to the Great Sumatran Fault, which runs the entire length of the island of Sumatra.

The Global Volcanism Program is not aware of any Holocene eruptions from Hulubelu. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Hulubelu page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Steam clouds rise above a line of fumaroles at Hulubelu volcano in SE Sumatra. Gunung Tangganus rises at the upper left, east of the North Hulubelu fumarole fields, which are aligned NE of and parallel to the Great Sumatran Fault, which runs the entire length of the island of Sumatra. Hulubelu, also spelled Ulubelu, is an elliptical, 4-km-long caldera or volcano-tectonic depression in SE Sumatra. The age of the latest eruptions from Hulubelu is not known, although solfataric areas, mud volcanoes, and hot springs occur at several locations.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
